“…Non-condensable gas soluted in liquid fuel has an impact on nozzle internal flow mainly during needle valve opening and closing (especially for pilot injection) and/or under super high injection pressure (hydraulic flip conditions). Our previous studies performed for the serial AZPI nozzle [61][62][63] showed that super-cavitation and hydraulic flips do not occur under pressure conditions corresponding to the real operating conditions of the diesel engine D243 that equips AZPI nozzles. For the investigated injection regime (corresponding to the rated operating conditions of the D243 diesel engine, see Figure 18), the main portion of the fuel (74% of cycle delivery) is injected into the cylinder when the nozzle needle is at the maximum lift.…”

“…The emulsifier keeps biofuel and water from separating, stabilizing the combination. Emulsified biofuel can be used in diesel engines without considerable modifications [242] and may even outperform diesel [243]. Renewable sources may emit fewer particulates and nitrogen oxides.…”

The environmental sustainability of agricultural and industrial vehicles, as well as of the transportation sector, represents one of the most critical challenges to the sustainable development of a nation. In recent decades, compression-ignition engines have been widely used in on-road and off-road vehicles due to their better fuel economy, autonomy, compactness, and mechanical performance (spec. the high torque values). Due to the consistent environmental impact of fossil fuels, scientists are searching for alternative energy sources while preserving the beneficial features of diesel engines. The utilization of blends of diesel fuel, biodiesel, and bioethanol fuel (referred to as “ternary blends”) is among the most promising solutions for replacing fossil fuels in the near term, allowing, at the same time, us to continue using existing vehicles until new technologies are developed, consolidated and adapted to the agricultural and industrial sector. These ternary blends can lower exhaust emissions without creating major problems for existing fuel-feeding systems, typically designed for low-viscosity fossil fuels. One of the concerns in using liquid biofuels, specifically biodiesel, is the high chemical affinity with conventional and bio-based lubricants, so the main parameters of lubricants can vary significantly after a long operation of the engine. The comprehensive literature review presented in this article delves into the technical challenges, the main research pathways, and the potential solutions associated with the utilization of biofuels. Additionally, it investigates the emerging application of nanoparticles as additives in lubricants and biofuels, highlighting their valuable potential. This study also discusses the potential implementation of bio-ethanol in ternary blends, offering a promising avenue for reducing reliance on fossil fuels while maintaining engine efficiency.

“…In the same context, Markov et al [96] investigated the physicochemical properties of rapeseed oil blends with diesel and emulsified multicomponent biofuel, studying its emissions, thermal efficiency, and nozzle inner flow, and then determined if the blends can be used as a replacement for diesel in internal combustion engines. The engine used to collect the data measurements was a diesel engine D-245.…”

In this article, the most important publications on the subject are compiled to highlight the progress in biodiesel production from tropical cultivars, including energy and environmental potential, raw materials, and the advantages and disadvantages of this biofuel. A critical and objective review of biodiesel production as an alternative fuel for power generation systems and its importance in the energy matrix was conducted. A survey of real applications, new computational and experimental trends, and proposals in internal combustion engines employing organic biofuel was performed. The main findings were as follows: (i) there is the possibility of integration and support in the energy matrix of different countries, as well as the competing with and complementing, energetically, other renewable energy sources, such as solar and wind; (ii) Jatropha curcas, sunflowers, soybean, Moringa oleifera, palm, cottonseed, castor, rubber seed, and coconut are tropical cultivars used to obtained oils into biodiesel; (iii) the findings can be utilized as a theoretical basis for future policies influencing the energy sector through regulatory measures.
